On what they miss most: Mark Williams said he misses making his morning coffee while Warwick Davis joked he missed the glue on his face from the prosthetics. Julie Walters said she missed the people she worked with.

Williams was ecstatic to find out that Mr. Weasley’s wand is now on sale.

The cast advise to look for the pensive hidden in the cupboard of Dumbledore’s office while doing the studio tour.

Room of Requirement is where cast would hide, but James Phelps and Warwick Davis often snuck off to the Great Hall when it was empty. “It’s spooky when empty, but calming and quiet,” they said.

James Phelps called visiting the sets again a “time warp to any time of our teenage years.”

The Burrow was listed as one of the harder sets to film on because it was small. The Room of Requirement was also a challenge because it got so hot.

Julie Walters said that whenever she and Helena Bonham Carter (Bellatrix Lestrange) saw each other on the day of filming their battle scene, they would shout from across the courtyard: “I’m gonna get you!” But Walters enjoyed filming that scene even though she says she later suffered from “wand arm.”

Bonnie Wright and Tom Felton both have replicas of their character’s wand.

On sets they would’ve have liked to film in: Tom Felton said he always wanted to film in the Burrow, while Julie Walters loved the Gyrffindor Common Room.

Bonnie and Tom joked you might see them around the studios as “secret tour guides.”
